' CAR-WINDOW.

SPECIFICATION forming part of Letters Patent No. 698,989, dated April29, 1902. Application filed July 25, 1901. Serial No. 69,658. (Nomodel.)

To all whom, it may concern: I

Be it known that I, ALEXANDER Monrlrr,

a citizen ofthe United States, residing at Gali-v fornia, in thecountyof Washington and Stateof Pennsylvania,-have invented certain newand useful Improvements in Oar-Windows,

air, from within and exclude dust, cinders, &c. p

This principle has long been recognized and applied to the deck or roofventilators of railway-cars.

I The primary object of the present inven-.' tion is to apply thisprinciple to car and other vehicle windows by providing a Window whichmay be opened outwardly or laterally at either.

vertical edge, determined bythe direction of movementof the car, wherebywith the for ward edge of the windowclosed in the casing and its manyedge opened outward the airis drawn or sucked from the car, carryingwith it all impurities, smoke from smoking-cars, &c. The air-currentsbeing in a reverse di rection from that which would admit dust, smoke,and cinders, the latter are entirely excluded. At the same timeexcessive drafts are prevented.

strong inflow of air,which carries with it dust,

smoke, and cinders, to the great annoyance of the passengers, andparticularly those who happen to be seated at the rear of the openwindows. Wire screens are-frequently provided to stop cinders; but evenif screens were effectual in excluding these and other impurities thestrong inward drafts would still be very objectionable. Furthermore,with this type'of window the impure air is not'removed, but remains inthe car in a highly-agitated state when thetrain is inmotion. With myimprovement all of these objectionable features' are obviated.

The invention consistsin the novel features of construction and in thecombination and arrangement of parts hereinafter fully declosedposition.

scribed and claimed, and illustrated by the accompanying drawings,wherein Figure l is a view in perspective of a portion of a railway-carequipped with my improved window, one ofthe windows being; shown closedand the other open. Fig. 2 is an outside elevation of two of the windowsin Fig. 3 is a sectional plan view of Fig.2, one of the windows beingshown open in full lines and open in reverse direction in dotted lines.Fig. 4 is a view of two of the windows, one window being shown in insideelevation and the other .window shown in vertical section. Fig. 5 is avertical cross-sectional view with the window closed. Fig. 6 is asectional plan View of a portion of a window with its lookingmechanism', the window being shown closed in full lines and open indotted lines. Fig. 7 is an outside elevation of the mechanism shown inFig. 6. Fig. 8 is a detail view of the window- .locking cams. Fig. 9 isa detail view illustrating a detachable key mechanism for operating thewindow-securing devices. Fig. 10 is a detail view of one of thesealing-strips.

Referring to the drawings,-2 repres'ents the wall of the car, 3 theprojecting window-sill,

and 4: an outwardly-projecting ledge at the top of thewindow-opening. r

5 represents the window frame or sash, which may be raised and loweredin the usual manner, the car-wall being constructed to permit of suchmovement. The projecting portion of sill 3 and ledge 4 are parallel, andthe distance therebetween isapproximately the same as the height of thesash. Secured to the vertical edges of the latter are the metallicT-shaped strips 6, which confine strips of rubber 7 for impinging theframe and sealing the window when the latter is closed. Secured to thetop and bottom edges of'the sash by metallic strips 8 are L-shapedrubber strips 8, the edges of which impinge the casing and sill 3, thussealing the window top and bottom. I

Mounted in the oar-wall adjacent each side of the windowopening are twohorizontal shafts 9, carrying T-sockets 10.' The arms of these socketsare connected by link 11, and uniting with this link is one end ofcoiled spring 12, the opposite end thereof being secured to thecar-wall, thus maintaining the window-securing mechanism normally inoperative position. Mounted eccentrically on the outer projecting end ofeach shaft 9 is head 13, with its inner cam-shaped face 14 in engagementwith the outer rounded portion- 6 of strip 0. Spring 2 is so arranged asto normally maintain heads 13 in this engagement, and thus each verticaledge of the window is secured at two points, preferably adjacent itsupper and lower ends. The cam-shaped faces let of heads 13 have aconstant wedging action on strip 6, the same being maintained by thepull of spring 12, so that the window is held securely closed. The innerends of the uppermost shafts 9 project within the car and carryhandles'15, or the shaft ends may be reduced and squared for thereception of removable key 19, as may be preferred, and by this meansthe shafts may be so turned as to disengage heads 13 from strips 6 andpermit of the released edge of the window being moved outward, as shownin Figs. 1 and 3. lVhen the window is thus turned, the strip 6 and heads13 at the opposite vertical edge thereof constitute a hinge, which hassufficient range to afiord the necessary swinging movement. The sash ispre vented from edgewise displacement by hookshaped spring-arms 16,secured to sill 3 and ledge 4. These arms also limit the outwardmovement of the window and impinge and hold the same open. The stop 17may also be arranged centrally on the sill for the purpose of limitingthe outward movement. The vertical edges of each window may be movedoutward or opened interchangeably, according to the direction ofmovement of the ear, the opening being always toward the rear. Thewindow may also be raised and lowered as may be required for cleaning orother purposes. For gaining access to the mechanism within the car-wallit is preferable to have vertical stop-strips 18 removable.

With the mechanism equipped with handles 15 the windows may be openedand closed by the passengers; but with the removable key 19, Fig. 9, thewindows are under the control of the car attendant,which may in somecases be desirable.

With all of the open windows opening rearward the impure air is drawnfrom the car and very effectual ventilation is had without subjectingthe passengers to annoying drafts. Also with this improvement a windowmay be open at one seat without disturbing the occupants of adjacentseats.

WVhile the invention has been shown and described as applied tocar-windows, the same may be used on buildings and other structures,withthe several adjustments available for securing effective ventilationregardless of the direction of prevailing winds or breezes and withoutcreating annoying drafts.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

1. The combination of a casing, an outwardly-movable window therein,andwindowsecuring devices mounted in the casing at opposite sides of thewindow between the upper and lower ends of the latter and adapted tooverlap the outer face of the window,whereby the window may be releasedat either vertical edge with the securing devices at the opposite edgeserving as a hinge, substantially as shown and described.

2. The combination of a casing, an outwardly-movable window thereinhaving its opposite vertical edges, rounded, movable securing devices onthe outer side of the casing at opposite sides of the window and adaptedto overlap the said rounded vertical edges thereof,whereby the windowmay be released and moved outward at either vertical edge with itsopposite rounded edge and the se curing devices overlapping the same andcooperating to form a hinge, substantially as shown and described.

3. The combination of a casing, an outwardly-movable window thereinhaving its opposite vertical edges rounded, rotatable headseccentrically mounted on the outer side of the casing at opposite sidesof the window and adapted to overlap the said rounded vertical edgesthereof, whereby the window may be released and moved outward at eithervertical edge with its opposite rounded edge and the heads overlappingthe same cooperating as a hinge, substantially as shown and de scribed.

4. The combination of a casing, an outwardly-movable window fittedtherein, shafts mounted transversely in the casing at opposite sides ofthe window, an operative connection between shafts at each side of thewindow whereby they are caused to turn together, and window-securingdevices mount ed on the shafts and operated thereby, substantially asshown and described.

5. The combination of a casing, an out wardly-movable window fittedtherein, two window-securing devices operatively mount ed in the casingat each side of the window, and a connection between saiddevices,whereby they are caused to operate together, substan tially asshown and described.

6. The combination of a casing having a window-opening, anoutwardlyprojecting horizontal ledge both above and below the opening,an outwardly-movable window fitted in the opening, and securing devicesoperatively mounted in the casing and adapted to overlap the verticaledges thereof, substan-- tially as shown and described.

7. The combination of a casing, a sash, metallic strips secured to thevertical edges of the sash, said strips having outward projections, andlocking devices adapted to removably engage the strip projections,substantially as shown and described.

8. The combination of a casing, the windowsash, metallic strips securedto the vertical side edges of the sash, the outer edges of said stripshaving outwardly-rounded projections and locking devices mounted in thecasing and adapted to removably engage the rounded portions of themetallic strips, substantially as shown and described.

9. The combination of a casing, a windowsash T-shaped metallic stripssecured to the opposite vertical edges of the sash, theoutwardly-projecting head portions of said strips being rounded, andheads eccentrically mounted in the casing and adapted normally tooverlap said rounded strip-heads, substan- V tially as shown anddescribed.

10. The cornbinationof a casing, an outwardly-movable window fittedtherein, the shafts mounted'transversely inthe casing, the-shafts oneach side of the casing being operatively connected for causing the sameto turn in unison, window-securing'devices carried by the shafts, and aspring for maintaining said devices normally in operative position,substantially as shown and described. In testimony whereof I'affix mysignature in presence of two witnesses.
